Serving lots of TIF from a Google Storage bucket

[iibrahimli]

I have the following:

• A Google Storage bucket with a lot of TIF images (each about 2-5 MB)
• A TiTiler instance that has access to the bucket

I want to use the TiTiler to serve the TIFs. I can request a single TIF using a URL like gs://bucket-name/path/to/the/image.tif, and e.g. I can view the TIF using the /cog/map endpoint. However, I have lots of TIFs in lots of folders, and it is impractical to add all of them separately. Is there a way to serve all of those files, what do I need to do, ideally without deploying any other software?

You have 3 solutions:

• GDAL VRT: create a .vrt of your files and add external overviews (You'll need to set GDAL_DISABLE_READDIR_ON_OPEN=FALSE to read the external overview).
• Create a MosaicJSON file and use the /mosaic endpoints if you are using default titiler.application endpoints
• Create STAC Items for all of you COGs and then use titiler.pgstac (You'll need to set up a PgSTAC Database
